Abstract: Изобретение относится к обработке металлов резанием и может быть использовано при глубинном периферийном финишном шлифовании материалов, предрасположенных к дефектообразованию, с регулированием теплового потока, направленного в деталь. Для осуществления способа используют сборный абразивный круг, содержащий неподвижный диск с крупнозернистым периферийным абразивным слоем для чернового шлифования и режущий орган с мелкозернистым периферийным абразивным слоем для чистового щлифования. Упомянутые слои выполнены аксиально-смещенными, а режущий орган - кольцеобразным и пружинным с перекрывающими друг друга концами, стянутыми пружиной растяжения. Режущий орган имеет возможность радиального перемещения посредством торового баллона. Такая конструкция позволяет производить переход с чернового на чистовой режимы обработки на ходу, что повышает производительность обработки, а наличие осцилляции зон резания снижает теплонапряженность шлифования и улучшает качество процесса. 3 з.п. ф-лы, 6 ил.
